[IPython-user] Detecting interactive mode reliably

[Francesc Altet]

Hi,

I'm trying to discover a way to detect whether the python interpreter
has been called interactively or not. My goal is to avoid costly
initialization calls in case the a program is not run interactively.

To be more specific, I only need to know whether the interpreter has the
readline() features activated or not. If they are (and only in this
case) then I need to preload some attributes on certain classe for easy
interactive introspection (i.e. using the TAB key).

Anyone has a clue on how to do this? (should be valid for Win as well)

Cheers,
